You work for a delivery service. With plan A, you can earn $5 per hour plus $0.75 per delivery. With plan B, you can earn $7 per hour plus $0.25 per delivery. How many deliveries must you make per hour with plan A to earn as much as plan B?

Respuesta :

You must make 4 deliveries per hour with Plan A to earn as much as Plan B.

Step-by-step explanation:

Plan A;

Earning per hour = $5

Per delivery earning = $0.75

Let,

x be the number of deliveries.

A(x) = 5 + 0.75x

Plan B;

Earning per hour = $7

Per delivery earning = $0.25

B(x) = 7 + 0.25x

For earning as much as B.

A(x) = B(x)

[tex]5+0.75x=7+0.25x\\0.75x-0.25x=7-5\\0.5x=2[/tex]

Multiplying both sides by 0.5

[tex]\frac{0.5x}{0.5}=\frac{2}{0.5}\\x=4[/tex]

You must make 4 deliveries per hour with Plan A to earn as much as Plan B.
